Symptoms traditionally linked to SIBO include bloating, diarrhea, constipation, and abdominal pain/discomfort. Steatorrhea may be seen in more severe cases. [4] Bacterial overgrowth can cause a variety of symptoms, many of which are also found in other conditions, making the diagnosis challenging at times. [4]
The ileocecal valve is typically located on the last fold before entry into the cecum and can be located from the direction of curvature of the appendiceal orifice, in what is known as the bow and arrow sign. [4] Intubation of the ileocecal valve is typically performed in colonoscopy to evaluate the distal, or lowest, part of the ileum.
A lower gastrointestinal bleed is defined as bleeding originating distal to the ileocecal valve, which includes the colon, rectum, and anus. [2] LGIB was previously defined as any bleed that occurs distal to the ligament of Treitz, which included the aforementioned parts of the intestine and also included the last 1/4 of the duodenum and the entire area of the jejunum and ileum.

Depending on the location of the volvulus, symptoms may vary. For example, in patients with cecal volvulus, the predominant symptoms may be those of small bowel obstruction (nausea, vomiting and lack of stool or flatus), because the obstructing point is close to the ileocecal valve and small intestine.
König's syndrome (synonym ileocaecal valve syndrome) is a syndrome of abdominal pain in relation to meals, constipation alternated with diarrhea, meteorism, gurgling sounds (hyper-peristalsis) on auscultation (especially in the right iliac fossa), and abdominal distension.
Intestinal lymphoma lacks symptoms that differentiate it from other conditions; diagnosis can only be confirmed through histological examination of tissue samples. [1] Intestinal tuberculosis can cause symptoms such as fever, night sweats, and ulcers in the transverse colon, along with a swollen ileocecal valve. Key tissue changes include ...
A Meckel's diverticulum, a true congenital diverticulum, is a slight bulge in the small intestine present at birth and a vestigial remnant of the vitelline duct.It is the most common malformation of the gastrointestinal tract and is present in approximately 2% of the population, [1] with males more frequently experiencing symptoms.
However, instances with symptoms and signs of a bowel obstruction occur, but with the absence of a mechanical obstruction, mainly in acute colonic pseudo-obstruction, Ogilvie's syndrome. [3] In 2023 the US FDA reported gastrointestinal ileus as an adverse effect of the medication semaglutide , with frequency and causal relationship unknown.
